You don't necessarily need one to record, you can use standalone preamps for that. If you don't plan on mixing with software on a computer, though, you'll need a mixer to do the mixing (imagine that...).
Perhaps, budget depending, you might do alright with a two channel preamp like the M-Audio DMP3, and a Yamaha MG12/4 mixer? Both come well recommended in the budget arena, and if you ever need extra preamps you can tap the insert points on the Yamaha. Just a thought.
